Abundance and co-occurrence of extracellular capsules increase environmental breadth: Implications for the emergence of pathogens

Fig 4

Cladogram of selected enterobacterial species and the capsule groups detected in their genomes.

The tree was built using the protein sequences of the 759 families of the core genome of Enterobacteria. Squares on the outer part of the tree indicate the presence (full) or absence (empty) of different capsule systems in the corresponding genomes. Background colour indicates the phylogenetic group of each genome. The size of the circles along the branches are proportional to bootstrap values ranging between 20 and 99. Absence of circles indicates a bootstrap of 100%.
